A system for transferring torque between modules in a concentrating solar collector array. A trough collector system includes at least two modules, each module including a reflector having a reflective surface shaped to concentrate incoming radiation onto a linear tube, and a structural lattice attached to the reflector. The modules are constrained to rotate about a common axis. A torque transfer connection directly connects the three-dimensional structural lattices of the two modules at a location removed from the axis of rotation. Torque is thus transmitted between the modules by a force couple acting on the module. Also described are a method of transferring torque between adjacent trough collector modules, and a three-dimensional structural lattice configured for use in the system and method. Mechanisms for accommodating thermal expansion and contraction of the array are described. A drive system is described that imparts torque to a module near an edge of the module.
